CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 276,005, dated April17, 1883. Application filed February 28, 1883. (No model.)

To all whom it may concern:

Be it known that we, OLIVER S. DALE and ABRAM BARNES, citizens of theUnited States,

residing at Michigan City, in the county of La Porte and State ofIndiana, have invented certain new and useful Improvements in Car-Oouplings; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanyin g drawings, and to the letters and figuresof reference marked thereon, which form apart of this specification.

Our invention relates to a car-coupling of the class operated by linkand pin; and the novelty consists in the construction and arran gementof parts, as will be more fully here'- inafter set forth, andspecifically pointed out in the claims.

The object of the invention is to provide a self-coup1ing attachment forrailroadcars, one which shall operate automatically to couple the carsas they come in contact, and one which shall allow the uncoupling to beperformed with the operator upon either side or upon the top of the car;and to these ends the invention consists, essentially, in the mechanismsfully illustrated in the accompanying draw-' ings, which form a part ofthis specification, and in which Figure 1 is a perspective view. Fig. 2is a sectional View, and Figs. 3, 4, and 5 are detail views.

Referring to the drawings, in which similar letters of referenceindicate like parts in all the figures, A represents a car, and B adrawhead secured thereon. The construction of the car and the particularmanner and means of securing the draw-head form no part of thisinvention. .The draw-head may be made in sections or in a singlecasting, and has the ordinary flaring mouth, I), which receives thecoupling-link M.

Within the draw-head is formed a recess, 0, which connects with andforms part of the link-chamber Z), adapted to receive a couplingdog, D,which is loosely pivoted in the drawhead at (Z in such manner that whenin position it will turn upon its pivot in a direction away from themouth of the draw-head to admit the link; but when turned in theopposite direction the free end will abut squarely on the bottom of thelink-chamber. This dog has a tongue, (1, formed upon its free end, whichtongue is adapted to be received within the link 0, and ears perforatedat (1 which receive apivotal pin, and thereby connects said dog D with avertical bar, F, the functions of which will be explained.

Secured at e to the draw-head B is a spring, E, having spring-jaws e,which have bearings upon the dog D upon each side of the tongue d, thespace between the jaws 6 being made to accommodate said tongue. It willthus be seen that as the cars come together the link will enter themouth I) of the draw head, strike the dog D to overcome the force of thespring E, turn the dog D on its pivotuntil the end of the link entersthe link-chamber, when the tongue (1 will drop into the link-cavity, andthe link be thus held locked in position, but having the necessary playto allow for the swaying of the cars.

To a stud, q, secured to the bumper or other convenient part of the car,is pivoted a link, G, to the free end of which in turn is pivoted thevertical bar F, at a point some distance below its upper end. This barhas pivoted at its upper end a hand-rod, H, which extends through properguides h, and is provided at its upper extremity with a ring or othercatch, it, adapted to engage a corresponding catch, h secured upon theend of the car to lock the rod H at its highest elevation against theconstant force of the spring E.

Pivoted to the car at t, upon either side of the center, is a lever, I,the inner end of each of which rests under the link G, while theopposite end extends outward, and when at rest is supported in abracket, i, but may be locked against the force of spring E by beingpassed under said bracket. It will thus be observed that the force ofthe spring E may be overcome by either the rod H or either of the leversI by the attendant, and the cars uncoupled and the locking-dog held outof enga gement with the coupling-link when desired.

Modifications in details of construction may be made without departingfrom the principle or sacrificing the advantages of our invention, theessential features of which will be readily understood, both inconstruction and operation, from the foregoing description. taken inconnection with the drawings.

Having thus fully described the invention, what we claim as new is-- 1.[he draw-head B, having recesses b 0, dog D d, and fiat spring E e, incombination with the link G, bar F, rod H, and the pivoted levers orhandles I, and means for holding their outer ends depressed,substantially as set forth 2. In combination with the draw-head B,having recess 0 and I), the dog D, formed "as OLIVER S. DALE.
